Layout of the cluster balloon in normal mode. You can pass the object's constructor with the ILayout interface
or the key for one of the standard layouts. Each standard layout has several customized options.
In standard layouts, geo object data fields are used by default:
clustercaption, balloonContentHeader, balloonContent, and balloonContentFooter (see Placemark).

'cluster#balloonTwoColumns' - Two-column layout. The left column lists the names of placemarks (the clusterCaption field of the placemark or balloonContentHeader, if the first field is not defined). The right column contains information about the geo object. Layout options:

balloonLeftColumnWidth — The width of the column with the list of objects in the cluster balloon, in pixels. Default value: 125

'cluster#balloonCarousel' - Information about the geo object is positioned in the center. The buttons to navigate to the previous and next geo object are positioned on each side. The lower part of the balloon has a quick navigation menu. Layout options:

balloonCycling — Cycle the list when navigating with the side arrows. Default value: true

balloonPagerSize — Number of navigational items in the lower panel. The default value depends on the type of device. For mobile phones it is 4, and for tablets and PCs — 9.

'cluster#balloonAccordion' - Information about geo objects in list format. Each list item is a small icon and the name of the placemark (the clusterCaption field of the placemark or balloonContentHeader, if the first field is not defined). The color of the icon corresponds to the color of the placemark. The color of the placemark is defined by the "iconColor" Placemark option. The icons might not always appear in Internet Explorer 8 and below. When a list item is clicked, information about the geo object is expanded beneath it. Layout options:

balloonAccordionShowIcons — Option that determines whether to display the geo object's icon in the 'cluster#balloonAccordionItemTitle' layout. This option is not used in Internet Explorer 8 and below. Default value: true

The height of the layout of the content of the balloon cluster.
The balloon cluster option balloonMaxHeight is not set by default,
because all standard layouts have fixed dimensions.
The standard value depends on the layout.

The width of the layout of the content of the balloon cluster.
The balloon cluster option balloonMaxWidth is not set by default,
because all standard layouts have fixed dimensions.
The standard value depends on the layout.

The layout containing the information about geo object.
The standard value depends on the layout.

Displayed to the right of the list in the 'cluster#balloonTwoColumns' layout. The standard value of 'cluster#balloonTwoColumnsItemContent'

Displayed in the center in the 'cluster#balloonCarousel' layout. The standard value of 'cluster#balloonCarouselItemContent'.

Displayed after the list item is clicked in the 'cluster#balloonAccordion' layout. The standard value of 'cluster#balloonAccordionItemContent'.

The set of fields received by this layout differs from the parent and matches the fields that received by the standard layout of a geo object balloon. Additionally, ownerProperties, ownerOptions and ownerState fields have been added to access the cluster data.

Layout of the cluster balloon in the "panel" mode. You can pass the object's constructor with the ILayout interface.
The available values are the same as in the 'balloonContentLayout' options.
If null, then the value of the 'balloonContentLayout' option is used.

Layout for cluster marker contents.
(Type: constructor for an object with the ILayout interface or the layout key). If you do not want to display the content of the placemark,
set the option value to null.

Array describing the icon for standard implementation of the cluster.
An icon description is made up of an object with the following fields:

href - Link to the image.

size - Array of two numbers representing the icon size in pixels.

offset - Offset of the icon relative to the anchor point of the object.

shape - Optional field. An object that implements the IShape interface or a JSON description of the geometry. Allows to specify the description of the icon geometry. If the parameter is omitted, a rectangular area around the icon will be considered as an active area for events (mouse over, mouse click).

The hotspot shape of the cluster.
Specified as a JSON description of the pixel geometry of the icon.
Use this option when creating your HTML layouts.
The coordinates of the figure geometry are counted from the anchor point.
